摘要
采用组织学、电镜方法对云南主要地方牛种大额牛、云南瘤牛、中甸牦牛、迪庆黄牛和中甸牛扁牛的肌纤维特性作了系统研究。５个牛种背最长肌的肌纤维直径（μｍ）分别为５７．４８±１．１５、１０９．４５±１．８４、１００．３８±６．２５、９０．３８±５．３１和９７．３５±９．６２；肌纤维密度（根／ｍｍ２）分别为２０１．５４±２．６６、１１５．４５±４．０４、１０６．３０±１０．１０、９０．３８±５．３１和９２．３５±９．６２；肌束内纤维数（根）分别为７３．２３±８．９０、３４．３２±８．７７、３６．３２±８．３０、４７．６２±８．９０和４０．４０±８．７９。肌节长度（μｍ）以大额牛公牛最长（１．７０６５），云南瘤牛去势公牛居中（１．４６７０），云南瘤牛公牛最短（１．２０５０）。
It is the first study on the striated muscles histologic structure characteristcs of the main native cattle in Yunnan. The eye muscle of Gayal,Zebu,Zhangdian yak,Diqing yellow cattle and Zhongdian cattle yak respectively are 57.48±1.15,109.45±1.84,100.38±6.25,90.38±5.31 and 97.35±9.62μm for muscle fiber diameter ;201.54±2.66,115.45±4.04,106.30±10.10 ,90.38±5.31 and 97.35±9.62 number/mm2 for muscles fiber density;73.23 ± 8.90,34.32±8.77,36.32±8.30,47.62±8.90 and 40.40±8.79 fiber number in per fasciulus. The length of Gayals muscle joint is 1.7065 μm and the castrated Zebu′s is 1.4760 μm and the Zebu′s is 1.2050 μm.
